Pratt has teamed up with 14-year-old Makenna Schwab, a Seattle Children's patient with Larsen Syndrome.

"I have a rare connective tissue disorder called Larsen Syndrome, and it effects my joints, causes deformities in my bones, and causes instabilities in my spine, and I have trouble with my breathing," Schwab tells KOMO News.

Schwab has had over 15 surgeries at Seattle Children's to save and change her life, she says.

Pratt, a Lake Stevens native, touted the contest and fundraiser in a video posted on his Instagram account.

In it, Pratt says, "Want to come visit me on the set of Jurassic World 2 in Hawaii? What? Yeah! You want to do it? Click the link in my bio!"

Every $10 donated is an entry to win, and you can enter as many times as you want. The winner gets a trip for four to hang out with Chris Pratt on the set of the Jurassic World sequel in Hawaii.

It also includes flights, a hotel stay, and a sneak peak of the film while on set.

Since Schwab was eight, Schwab has fundraised for the hospital annually, and has brought in at least 2,000 toys and raised $73,000.

In just five days, the pair has passed $200,000, and all proceeds benefit the orthopedics department at Seattle Children's.
